Idle RPM abnormal drop

[rst619]

Under warranty pa po pala, so eto po sabihin mo:

As I start the engine, the idle rpm abnormally drops down near zero then after approximately 3 secs it goes up to its normal idle rpm of 650 and I already encountered this twice

[speedyfix]

could be the servo or a dirty throttle. shouldn't be that hard to fix on a relatively new car.

[banawe]

pa check mo yug air cleaner mo ... or baka may hose lang natangal sa may throttle

[oj88]

Is the engine cold or warm?

[bambino]

it has to be checked by the tech , pero you can ask the dealership to get it scanned for any codes or to perform some basic tests.

i.e.smoke test for any vacuum leaks or a throttle body cleaning maybe.

hi Yen,

just saw this thread. i had the same problem with my Sentra as yours after i had my headlights changed to XP sa Petron. I don't know if meron sila nagalaw or something, but the idle RPM dropped from 850 to 400 with A/C, 300 if walang load.

brought it to NGO- Libis, kinabitan lang ng Consult II, then dun in-adjust yung idle RPM back to 850. ayos na ulet.. la pang 10mins.

SA Remo ang nag-assist sa ken. Hope yours get fixed as well.

Cheers!

Hi Sir Carlo,

Dinala ko rin yung auto sa NWA ginamitan din ng consult II tapos nag-idle air volume learn. Ok na siya ngayon.
